The prognostic value of circulating tumor cells (CTCs) in patients with squamous cell carcinoma of the head and neck (SCCHN) is controversial. The objective of this study was to evaluate the prognostic value of CTCs in patients with SCCHN by conducting a meta-analysis. We systematically searched scientific literature published before June 10, 2014, using the PubMed, ScienceDirect, Cochrane Library, and EMBASE databases. Studies evaluating the correlation of CTC status with tumor-node-metastasis (TNM) disease stage, nodal involvement, and disease progression (recurrence or metastasis) in patients with SCCHN were selected for the analysis. Pooled odds ratio (OR) and 95 % confidence interval (CI) were calculated using the fixed-effects model or the random-effects model in the presence of heterogeneity. Our analysis consisted of eight studies, enrolling a total of 433 patients. The disease progression (recurrence/metastasis) rate in the CTC-positive patients was significantly higher (OR 3.44; 95 % CI 1.87-6.33; p < 0.01) compared with the patients without disease progression. However, there was no significant difference between TNM disease stage III-IV and stage I-II in the presence of CTCs (OR 1.54; 95 % CI 0.87-2.72; p > 0.05). CTC status did not correlate with nodal involvement (OR 1.20; 95 % CI 0.67-1.90; p > 0.05). This meta-analysis indicates that detection of CTCs has a predictive value in patients with SCCHN, particularly those with tumor progression. The presence of CTCs in patients with SCCHN has a poor prognosis compared with the patients without CTCs. Detection of CTCs might be served as a prognosticator in patients with SCCHN. Further studies based on homogeneous populations are warranted to confirm these findings.
We discovered that ISET is more suitable than the CSS for detecting CTCs in RCC patients. The presence of CTCs/CTMs in RCC patients correlated with higher TNM stages, suggesting that the presence of CTCs could be a prognostic marker in RCC patients.
Abstract. The regeneration of muscle tissue has been achieved using multipotent mesenchymal stem cells in mouse models of injured skeletal muscle. In the present study, the utility of multipotent human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) in the treatment of Becker muscular dystrophy (BMD), a genetic disease where muscle tissue fails to regenerate, was examined in members from a pedigree affected by BMD. The disease status was evaluated in 4 affected pedigree members (II1, II2, II3 and III2; aged 50, 46, 42 and 6 years, respectively). The transplantation of the hUC-MSCs (performed on 3 patients, I2, II3 and III2) was performed by infusion with an intravenous drip over a 30-min period, and the patients were evaluated at 1, 3, 4 and 12 weeks following the procedure. The evaluation was based on physical characteristics, as well as on molecular testing for serum creatine kinase (CK) and lactate dehydrogenase (LDH) levels and a histological examination of muscle biopsies. The patients suffered no adverse reactions in response to the transplantation of the hUC-MSCs. At 1 week following transplantation all 3 patients showed improvement in the muscle force of the limbs, muscle size and daily activity. The walking gait of patient III2 had improved by 1 week post-transplantation and reached a normal status by 12 weeks. Serum CK and LDH levels were decreased relative to the baseline levels. A histological examination of muscle biopsies displayed no obvious tissue regeneration. In conclusion, the treatment of patients with BMD using hUC-MSCs was safe and of therapeutic benefit that lasted for up to 12 weeks. hUC-MSCs are, therefore, a potential cell therapy-based treatment option for patients with muscular dystrophies.
Primary hemangioendotheliomas (HEs) of the spleen are rare, low-grade borderline-malignant vascular tumors. To date, only a few splenic HE cases have been reported in adults. In infants, one 9-year-old male patient has previously been reported, and the patient succumbed to the disease shortly following surgery. Currently, the clinical treatment and prognosis of the disease remains challenging to define, due to the extremely low number of cases reported. The current report presents the case of a 9-year-old pediatric patient with splenic HE, who survived with no recurrence or complications following a partial splenectomy. Additionally, a literature review was conducted to analyze the treatment and prognosis of the disease.
